Constant was not wrong with this.

The current internal combustion engine is also fuel combustion, but in the cylinder, the cylinder block is iron and there is a heat dissipation device outside, while the piston is iron or aluminum. At the same time, among the four strokes, only one is combustion, and the other three are not in a high temperature and high pressure environment, so the piston can also dissipate heat during back and forth.

However, the newly studied jet is different. The turbine blades on the last are always in high temperatures. If there is no suitable high-temperature material, the turbine blades will soon burn out and their lifespan will be quite short.

As an excellent technician, when he started designing, he keenly realized that materials are the first problem they will encounter. In contrast, the design of turbines is not that important.

It was because he couldn't find the right materials that Constant had not made any progress, just as if Edison had to test so many materials in order to invent electric lights in history, and he also needed to find the right materials.

So what if you get a German prototype?

Even if the most advanced means are used to analyze the elements in the other party's turbine blades, they still cannot produce without knowing the production process and have no other function except providing them with ideas.

When Hoover heard this statement, he was extremely disappointed.

And he could also imagine that when the President heard this news, he would be even more disappointed and could not quickly develop the jet, so that America would not be able to fight in the next battle!

Now, he didn't know that the fighter jet that had been acquired was burning into a pile of scrap iron. The American intelligence personnel present were also blasted by 20mm machine cannon bullets, and their bodies became pieces of minced meat. Germany's revenge came very fiercely.

Only that medical car is left.

"Quick, hurry, hurry!" A leading captain kept urging in the medical car: "They dare not attack us. As long as we reach Frobishebe in front, we will be safe."

The island of Baffin is also sparsely populated, and they chose the simulated airport, which is even more inland. Now, they have to travel more than 100 kilometers to get there.

At that time, as long as you enter the city, you can throw away the plane above your head, and they can easily take a boat and leave here.

The car was moving forward on the ice field. Although the speed had reached its maximum, the captain was still uneasy. With the bombing of the airport and the plane was destroyed, the captive in their hands was already the final result.

Several military doctors examined the captive's body, but they were fine. They just fainted and should wake up within a few hours.

Finally, I gradually saw the city ahead, and at the same time, it was getting dark outside. As winter approached, the night here would become longer and longer. As long as it became dark, the other party would not be able to see it!

At this moment, suddenly, a huge rumbling sound came from a distance. Looking to the side, the car window on the side had a thick layer of frost. He held a card and scraped the frost hard. Now he saw clearly that they were two strange-shaped planes, with a large turntable on the top, which was rotating, which was very similar to the helicopter written by Da Vinci.

As if confirming his guess, the plane hovered, and then slowly descended, just ahead of their road, less than one meter above the ground, and stopped steadily.

A rope hung down from above, and a fully armed warrior slipped down smoothly from above.

"Quick, go around!" In an instant, the captain knew that there was a lot of trouble. The person who came here must be the Germans, who came to intercept his own side and save their pilot!

The driver was also cruel and gritted his teeth and turned the steering wheel. The car left the rugged road and headed towards the side.

The wheels were crushing deep ruts in the snow. He stepped on the accelerator to the bottom. The cars were moving forward with difficulty in the black smoke. At the same time, the people who came off the helicopter line formed a scattered line and rushed towards them quickly!

After the other party got down, he put down the sled from his back and actually came over for skiing!

The German special forces are so adaptable. When they are training in Finland, they mastered the skills of skiing. If they walk directly, they will step into a deep snow nest, and they will be very slow when skiing.

Now, Morris was in the front, drifting snow, as if flying on the snow, heading towards the white medical car.

"Hurry, hurry!" the captain shouted.

The driver's accelerator was already at the end, and he was also very anxious. At this moment, suddenly, a resonant sound came from the car, which was very loud. At the same time, the car stopped moving.

No, the wheels are stuck!

A wheel was idling, digging the snow nest, getting bigger and bigger, sinking the wheel deep inside, and the driver drove forward, no, and then reversed.

Just as we started to reverse, there were already figures outside.

"Get out, get out immediately!" Morris shouted at the person inside, holding up the automatic rifle in his hand.

It was so easy, it didn't look like a special combat mission, it was as smooth as a training exercise.

The door of the car opened, and inside, Americans came out one by one with their hands raised.

Morris didn't care about them. When everyone inside came out, the two soldiers went in and carried the pilot Ted out of the helicopter.

Soon, the helicopter took off again and rolled up the snowflakes around it. It was clean and neat for only ten minutes, leaving only these Americans in the snow, staring at the helicopter in a daze.

After half a month of struggle, I ended up like this. Most of the people involved in the operation died and nothing was found, only the wreckage of a plane was left.

The roar in the sky disappeared, and Baffin Island entered darkness and calm again. When he heard the news, Donovan could no longer suppress his anger.

When Donovan finished venting, the adjutant on the side said carefully: "After all, we still got the wreckage. The wreckage is of great significance to us. In addition, only one of the two attacking aircraft reached our disguised base, and where did the other one go?"

This matter is not over yet. After all, there is another plane that is attracted by its own side and away from their base. At the same time, the navigation when returning is interfered with, maybe they will be on the way?

Yes, can you still complete the mission if you find this plane?
Chapter completed!
